A convex lens is placed between object and a screen. The size of object is 3 cm and an image of height 9 cm is obtained on the screen. When the lens is displaced to a new position, what will be the size of image on the screen?

Options

  1. A2 cm
  2. B6 cm
  3. C4 cm
  4. D1 cm

Correct answer

D. 1 cm

Step-by-step solution

From displacement method size of object, O= I₁ I₂ Here, O=3 ~cm , I₁=9 ~cm , array ll & 3= 9 I₂ array or I₂=1 ~cm
